I am trying to run the HcmCompWorkbenchWorkarea.jspx page locally from my Fusion Customization Application on JDeveloper (Customization Role).
There is a 'Search and Select: Manager' drop down on this page where I can select a Manager after searching on a popup that gets opened on the drop down.
For some reason this search popup does not show any results. Prevously whenI had this issue, I replaced my system-jazn-data.xml from my colleauge and after rebooting the laptop
it worked, but now it does not. I am thinking its got something to do with the Security. On my Customization APplication's Project I did set this project property:

Try to add additional property -Djbo.debugoutput=console which will enable the console output for the sql queries executing behind the scene.
Try to debug based on those sql queries like what query is getting constructed and is it really expected to return any results.

ADFbc Logging definitely works; we use it regularly in development. When your WLS starts up, check the console log to make sure the parameter is passed correctly to the JVM. If you google "-Djbo.debugoutput=console", you should find lots of information around this topic as it's generic and not specific to Fusion Apps.
